Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically a positioning device for processing anti-light pollution lenses. Background Technology

[0002] Positioning devices for anti-light pollution lens processing are key equipment in the lens processing field. They ensure that the lens can be fixed and clamped during the processing, requiring high stability, processing accuracy and ease of operation.

[0003] The existing publicly available technical solution (CN218170972U) discloses a positioning device for processing anti-light pollution lenses, including: a base, a base plate, a connecting rod, and a lens. The base plate is fixedly installed on the surface of the base, and the connecting rod is symmetrically slidably installed on the side of the base plate. Compared with the traditional positioning device for anti-light pollution lenses, this device can support and position the middle part and the two sides of the lens respectively during use, ensuring the stability of the lens during grinding and cutting. It also eliminates the need to use specific glue to bond and position the lens, making the positioning and disassembly of the lens more convenient and stable, and speeding up the overall work efficiency.

[0004] The above technical solution uses a suction cup to fix the lens and sets auxiliary positioning devices on both sides to improve the stability of lens clamping. However, after clamping the lens, when it is necessary to adjust the direction of the lens, the lens needs to be released and then clamped again, which is inconvenient to use. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing positioning device uses a suction cup to fix the lens and sets auxiliary positioning devices on both sides to improve the stability of lens clamping, but after clamping the lens, when it is necessary to adjust the direction of the lens, the lens needs to be released and clamped again, which is inconvenient to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A positioning device for processing anti-light pollution lenses includes a base plate assembly; a suction cup adsorption assembly for positioning and holding the lens; and a rotary guide assembly for rotating the lens angle.

[0009] The suction cup adsorption assembly includes: a silicone suction cup; a rotating chamber disposed at the bottom of the silicone suction cup; a transmission gear ring fixed to the outside of the rotating chamber; and a drive gear meshing with the side of the transmission gear ring.

[0010] The rotary guide assembly includes: a limiting rubber wheel rotatably mounted above the silicone suction cup; and a lifting plate that can be raised and lowered above the limiting rubber wheel.

[0011] As a further embodiment of this invention, the suction cup adsorption assembly further includes: a gear knob fixed to the top of the drive gear; and a connecting rod fixed between the rotating chamber and the transmission gear ring.

[0012] As a further embodiment of this utility model, the suction cup adsorption assembly further includes: a guide bracket fixed inside the rotating chamber; a telescopic rod telescopically installed inside the guide bracket; a return spring sleeved on the outside of the telescopic rod; a connecting air pipe passing through the inside of the telescopic rod; and a vacuum generator fixed to the end of the connecting air pipe.

[0013] As a further improvement of this utility model: the vacuum generator is connected to the suction hole of the silicone suction cup through a connecting air pipe, and the telescopic rod is sleeved with the guide bracket.

[0014] As a further embodiment of this utility model: the base plate assembly includes: a positioning base plate installed on the bottom of the silicone suction cup; and a guide groove formed on the top end face of the positioning base plate.

[0015] As a further embodiment of this utility model, the rotary guide assembly further includes: a support frame slidably installed inside the guide groove; a bidirectional lead screw rotatably installed inside the support frame via a lead sleeve; and a servo motor fixed to one end of the bidirectional lead screw, wherein the servo motor is fixed to the side of the positioning base plate by bolts.

[0016] As a further embodiment of this utility model: the rotary guide assembly further includes: a clamping screw rotatably mounted on the support frame near the silicone suction cup; a clamping knob fixed to the top of the clamping screw; and the lifting plate mounted on the bottom of the clamping screw via a bearing.

[0017] As a further embodiment of this utility model, the rotary guide assembly further includes a bracket welded to the bottom of the lifting plate, and the limiting rubber wheel is rotatably installed inside the bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model uses a suction cup adsorption component to position and clamp the lens in conjunction with a limiting rubber wheel. The active gear on the suction cup adsorption component can drive the transmission gear ring to rotate, thereby driving the rotating chamber to rotate through the connecting rod on the inner side of the transmission gear ring. This allows for angle adjustment of the lens placed on top of the silicone suction cup, and the limiting rubber wheel can rotate synchronously without damaging the lens.

[0020] 2. This utility model can adjust the movement of the support frame according to the lens diameter by setting the rotary guide component. The lifting plate is pushed down by the clamping screw, so that the limiting rubber wheel is close to the lens for easy clamping of the lens. Attached Figure Description

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0031] Please see Figure 1 , Figure 4 and Figure 6 This is the first embodiment of the present invention.

[0032] This embodiment provides a positioning device for processing anti-light pollution lenses, including a base plate assembly 1; a suction cup adsorption assembly 3 for positioning and holding the lens; and a rotary guide assembly 2 for rotating the lens angle.

[0033] The suction cup adsorption assembly 3 includes: a silicone suction cup 301; a rotating chamber 302 disposed at the bottom of the silicone suction cup 301; a transmission gear ring 308 fixed to the outside of the rotating chamber 302; and a drive gear 310 meshing with the side of the transmission gear ring 308.

[0034] The rotary guide assembly 2 includes: a limiting rubber wheel 208 rotatably mounted above the silicone suction cup 301; and a lifting plate 206 that can be lifted and lowered above the limiting rubber wheel 208.

[0035] Specifically, the suction cup adsorption assembly 3 also includes: a gear knob 311 fixed to the top of the drive gear 310; and a connecting rod 309 fixed between the rotating chamber 302 and the transmission gear ring 308.

[0036] Furthermore, the gear knob 311 can drive the drive gear 310 to rotate, and the drive gear 310 can drive the transmission gear ring 308 to rotate through its teeth, thereby driving the rotating chamber 302 to rotate through the connecting rod 309 inside the transmission gear ring 308, so that the angle of the lens placed on top of the silicone suction cup 301 can be adjusted.

[0037] Specifically, the suction cup adsorption assembly 3 also includes: a guide bracket 305 fixed inside the rotating chamber 302; a telescopic rod 307 telescopically installed inside the guide bracket 305; a return spring 306 sleeved on the outside of the telescopic rod 307; a connecting air pipe 303 passing through the telescopic rod 307; and a vacuum generator 304 fixed to the end of the connecting air pipe 303.

[0038] Furthermore, the lens is placed on top of the silicone suction cup 301. Under the action of gravity, it can press down on the return spring 306, and then the telescopic rod 307 can slide inside the guide bracket 305. The inner cavity of the guide bracket 305 can be used to place the connecting air tube 303.

[0039] Specifically, the vacuum generator 304 is connected to the suction port of the silicone suction cup 301 via the connecting air pipe 303, and the telescopic rod 307 is sleeved with the guide bracket 305.

[0040] Furthermore, when the vacuum generator 304 is working, it creates a vacuum negative pressure state between the silicone suction cup 301 and the lens by connecting the air pipe 303, thereby fixing and positioning the lens.

[0041] In use, the lens is placed on top of the silicone suction cup 301. Under the action of gravity, the return spring 306 can be pressed down, and then the telescopic rod 307 can slide inside the guide bracket 305 while activating the vacuum generator 304. Through the connecting air pipe 303, a vacuum negative pressure state is formed between the silicone suction cup 301 and the lens, thereby fixing and positioning the lens. Since a rotatable limiting rubber wheel 208 is set on the top of the lens, the limiting rubber wheel 208 can contact the lens and clamp it a second time. When it is necessary to adjust the direction of the lens, the gear knob 311 can be rotated. The gear knob 311 drives the drive gear 310 to rotate, and the drive gear 310 drives the transmission gear ring 308 to rotate through the teeth. In turn, the connecting rod 309 inside the transmission gear ring 308 drives the rotating chamber 302 to rotate, so that the angle of the lens placed on top of the silicone suction cup 301 can be adjusted. At this time, the limiting rubber wheel 208 on the top of the lens can rotate. The limiting rubber wheel 208 is made of rubber to avoid damaging the lens.

[0042] In summary, the suction cup adsorption component 3, in conjunction with the limiting rubber wheel 208, can position and clamp the lens. The drive gear 310 on the suction cup adsorption component 3 can drive the transmission gear ring 308 to rotate, thereby driving the rotating chamber 302 to rotate through the connecting rod 309 inside the transmission gear ring 308. This allows for angle adjustment of the lens placed on top of the silicone suction cup 301, and the limiting rubber wheel 208 can rotate synchronously without damaging the lens. Example

[0043] Please see Figure 2 , Figure 3 and Figure 5 This is the second embodiment of the present utility model.

[0044] Specifically, the base plate assembly 1 includes: a positioning base plate 101 installed on the bottom of the silicone suction cup 301; and a guide groove 102 formed on the top end face of the positioning base plate 101.

[0045] Furthermore, the silicone suction cup 301 is located on top of the positioning base plate 101.

[0046] Specifically, the rotary guide assembly 2 also includes: a support frame 201 slidably installed inside the guide groove 102; a bidirectional lead screw 204 rotatably installed inside the support frame 201 via a lead screw sleeve; and a servo motor 203 fixed to one end of the bidirectional lead screw 204, the servo motor 203 being fixed to the side of the positioning base plate 101 by bolts.

[0047] Furthermore, the servo motor 203 can drive the bidirectional lead screw 204 to rotate, and then the bidirectional lead screw 204 can drive the support frame 201 to slide inside the guide groove 102 through the lead sleeve, so as to facilitate the adjustment of the position of the support frame 201 according to the lens diameter.

[0048] Specifically, the rotary guide assembly 2 also includes: a clamping screw 205 rotatably mounted on the support frame 201 near the silicone suction cup 301; a clamping knob 202 fixed to the top of the clamping screw 205; and a lifting plate 206 mounted on the bottom of the clamping screw 205 via a bearing.

[0049] Furthermore, rotating the clamping knob 202 can drive the clamping screw 205 to rotate, and the clamping screw 205 can push the lifting plate 206 to move downward, thereby pushing the limiting rubber wheel 208 at the bottom of the lifting plate 206 closer to the lens, making it easier to clamp the lens.

[0050] Specifically, the rotary guide assembly 2 also includes: a bracket 207 welded to the bottom of the lifting plate 206, and a limiting rubber wheel 208 rotatably installed inside the bracket 207.

[0051] Furthermore, the limiting rubber wheel 208 can rotate inside the bracket 207. When clamping the lens, the rotation of the lens can simultaneously drive the limiting rubber wheel 208 to rotate.

[0052] In use, when it is necessary to clamp the lens, the lens is placed on top of the silicone suction cup 301. At the same time, the position of the limiting rubber wheel 208 can be adjusted according to the lens diameter, so that the limiting rubber wheel 208 moves above the lens. During adjustment, the servo motor 203 is started, and the servo motor 203 drives the bidirectional lead screw 204 to rotate. Then, the bidirectional lead screw 204 drives the support frame 201 to slide inside the guide groove 102 through the lead sleeve, which facilitates the adjustment of the position of the support frame 201 according to the lens diameter. Then, the clamping knob 202 is rotated, which drives the clamping screw 205 to rotate. The clamping screw 205 pushes the lifting plate 206 to move downward, thereby pushing the limiting rubber wheel 208 at the bottom of the lifting plate 206 closer to the lens, which facilitates the clamping of the lens. The limiting rubber wheel 208 can rotate inside the bracket 207. When clamping the lens, the rotation of the lens can drive the limiting rubber wheel 208 to rotate at the same time.

[0053] In summary, the rotating guide assembly 2 can adjust the movement of the support frame 201 according to lenses of different diameters. The clamping screw 205 pushes the lifting plate 206 downward, so that the limiting rubber wheel 208 is close to the lens for easy clamping of the lens.
